2,2'-Bis(dicyclohexylphosphino)-1,1'-biphenyl → N-Methyl-N-(4-{2-[3-(4-methyl-piperazin-1-yl)-phenylamino]-[1,2,4]triazolo[1,5-a]pyridin-8-yl}-phenyl)-methanesulfonamide

Participants

Reaction Steps

N-Methyl-N-(4-{2-[3-(4-methyl-piperazin-1-yl)-phenylamino]-[1,2,4]triazolo[1,5-a]pyridin-8-yl}-phenyl)-methanesulfonamide was prepared from N-[4-(2-amino-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-phenyl]-N-methyl-methanesulfonamide (75.0 mg, 0.236 mmol) and 1-(3-bromo-phenyl)-4-methyl-piperazine (70.0 mg, 0.274 mmol) with 2,2′-bis-dicyclohexylphosphanyl-biphenyl (26.0 mg, 0.0476 mmol) as the ligand in an analogous manner to Step 2d and was isolated as a tan solid (0.038 g, 33%). MP=202-204° C. 1H NMR (400 MHz, CDCl3, δ, ppm): 8.43 (d, J=6.9 Hz, 1H), 8.06 (d, J=7.4 Hz, 2H), 7.58 (d, J=7.1 Hz, 1H), 7.52 (d, J=7.4 Hz, 2H), 7.36 (s, 1H), 7.25-7.19 (m, 1H), 7.00-6.95 (m, 2H), 6.83 (s, 1H), 6.59 (d, J=8.4 Hz, 1H), 3.39 (s, 3H), 3.30-3.25 (m, 4H), 2.90 (s, 3H), 2.63-2.58 (m, 4H), 2.37 (s, 3H).
